- 3 shows a schematic representation of an accident event.
- the accident event shown in FIG. 3 consists of a collision of a vehicle 100 with a collision object 300, more precisely in an impact on an obstacle or collision object 300, for example in the form of an external vehicle while the vehicle 100 is traveling straight ahead Driver of vehicle 100 is on vehicle 100 during the accident event.
- the vehicle 100 is the vehicle from FIG. 1 or a similar vehicle which has the emergency call system from FIG. 1 or a similar emergency call system.
- the kinetic energy that is to be dissipated in the event of the accident and thus the severity of the driver's injury can be reliably determined from the deceleration and the remaining speed before the impact or the start of the collision. Criteria for immediate or delayed emergency calls are, for example, the vehicle speed at the start of the collision and the rate of deceleration.
- Biomechanical comparative values and information from accident databases can be used to decide whether to make a direct, immediate or delayed emergency call.
- FIG. 4 shows a schematic representation of an accident event.
- the accident event shown in FIG. 4 consists in cornering of a vehicle 100 with a loss of control over vehicle 100 on the part of the driver.
- the vehicle 100 is the vehicle from FIG. 1 or a similar vehicle which has the emergency call system from FIG. 1 or a similar emergency call system.
- a division into the first case 401 and the second case 402 is illustrated.
- the driver is on the vehicle 100.
- the device from FIG. 1 or a similar device is used to determine when and whether the driver has separated from the vehicle 100.
- the activation of the emergency call is delayed by the waiting period of, for example, 20 seconds.
- a basis for determining the driver's injury severity 125 is the energy that has to be dissipated on or in his body if the vehicle 100 has a fall or a collision. Should the driver be in the If you have separated the course of the vehicle 100 before the collision object 300 arrives, the speed at the time of separation is a measure of its kinetic energy, which is to be dissipated in the event of the accident. Therefore, according to an exemplary embodiment, this relevant point in time is recognized by means of the device 100 or by executing the method 200 in order to react accordingly with the emergency call strategy. In this consideration, it is assumed that there are no sensors on the driver or front passenger. In order to differentiate between the various situations or scenarios of accident events, in particular the entire historical course or course of the driving dynamics data and / or operator input data represented by the at least one sensor signal 104 is to be considered.
- a dynamic, controlled or regulated movement sequence of a vehicle 100 in the form of a two-wheeler with a driver is a constant sequence of compensation of forces or moments. Mention should be made here of cornering force, inclination and speed as well as centrifugal force and centripetal force.
- a transition from such a regulated sequence to a simple physical sequence, e.g. B. a tipping over, or a chaotic process, z. B. a rollover is assessed as the point in time at which the driver lost control.
- Stable cornering depends on the speed and the cornering forces. For a defined curve radius, this can be detected by measurement by means of the sensor device 102 located on the vehicle 100 in the form of an inertial sensor system. In order to clearly identify the presence of the driver on the vehicle 100, the sphere of activity between the driver and the vehicle 100 is determined via the steering of the vehicle 100.
- Any steering movement of a front wheel of vehicle 100 with a steering angle that is less than 90 degrees to the contact point causes tilting of the rotating wheel. This results in an angular momentum with a forced precession.
- the vehicle 100 is forced into an opposite circular path.
- the centripetal force which acts in the overall center of gravity, causes a moment that counteracts the precession.
- the change between the individual effects is determined by the driver. Driving straight ahead is defined here as cornering with an infinite radius.
- Device 120 determines this state, the relationship between speed and typical mass of the driver is used to determine the energy to be dissipated and thus the severity of injury 125.
- the decision on the trigger delay of the emergency call follows from this. In the event of a driver trapped under the vehicle 100, the conditions for driving straight ahead apply.
- an exemplary embodiment comprises an “and / or” link between a first feature and a second feature, this is to be read in such a way that the exemplary embodiment according to one embodiment has both the first feature and the second feature and, according to a further embodiment, either only the has the first feature or only the second feature.
